To all wholn it may concern: i

Be it known .that we, ARTHUR l. CHnis- 'riAN and MARVIN S. BERRY, citizensofthe United States, residing at Beggs, in the county of Okmulgee and A.State of Oklahoma, have invented a new and useful Bafi 'fle for Oil Tanks, of which the following is qucnce is that tion, the tan a specification.

By way of explanation, it may be stated that sediment. invariably collects in the bottom of a tank containing oil. It is necessary to draw ofi' ythe sediment, subject to certain regulations, before a salejof oil can 'be effected. In drawing off the sediment, there is a downward draft of oil, and the consea large amount-4 of oil is wasted. b The foregoing being understood, it may be stated` that this invention aims1 to piovide a novel form of baflie to prevent a downward suction, thereby obviating the wasting of oil duringthe process of extractiiigthe sediment and foreign matter from an oil tank.

It is within the province of the disclosure to improve generally andto enhance the vutility of devices ofthat type to which the invention appertains. i With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination 'and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown caribe made without departing from the spirit of the invention. 4

In the accompanying drawings Figure 1 shows in4 horizontal section, a portion of an oil tank wliereunto the device forming the` subject matter of this application has been applied; Figure 2 is a transverse section of the structure shown in Figure l; yFigure 3 isa section taken iii aplane at right anglesto the lcutting plane in Figure 2; Figure 4 is a fraginental horizontal section showing a modified form'of the invention; Figure 5 isavertical section showing the structure delineated in Figure 4;Y

'the baille used in Figure 6; Figure` 8 is a plan showinof a modified form'of the invenck appearing in section; Figure y 9 is a transversel section of the. structure shown in .Figure S; Figure l0 is a vertical -sectional view showing a modified form of "the invention, parts appearing in elevation;

Figure llvis a vertical section showing another n'iodihcatio'n ofthe invention, parts appearing in elevation; Figure l2 is a plan ,of the baille used in Figure '11.

In Figures l, 2 andB, the'nunieral l marks a tank for the reception of ori and the like.

.An outlet 2 isvassembled with the bottom of the tank l and is controlled by a valve 3. Disposed within the tank l andY above the outlet 2 is a baille el, in the forni of a plate. If desired, the baiile a may be inclined downwardly and inwardly to a .slight extent,.l as shown in Figure' 3 so as'to shed any sediment vwhichmay settle thereon. The forward edge of the baiiie l is provided with a flange .curved to conform to the wall ot' the tank i and' fitting thereagainst. ii iiexible operating vmember 6 is assembled with the bailie 4 and extends upwardly therefrom. The numeral 7 marks a support or rod having enlarged flattened portions 8. The baiiie 4 has a bearing 9 receiving the. rod or support 7 and forming a hinged connection between the baille and the rod, the bearing 9 being cut away as at 10 to clear the 'flattened and enlarged portions of the rod or support i. AIn some or all of the partsS of the rod 7 are mounted adjustable legs 1l, preferably 14. are pivoted to the ends of the support 7 the outer endsA of the links being pivotally f assembled with brackets 15 connected with the tank 1.

'.'It will be obvious'that since the baille 4 is disposed above the'outlet 2, there will be no direct draft of oil into the outlet 2. The consequence is, that .when thevalve 8 is opened., all of the sediment and foreign matter will\be drawn off the bottom ofthe tank l with a minimum waste of oil, tlieie beingno appreciable rdown draft or flow of oil from the tank 1 into the outlet 2. The operator may swing the baie lv into a vertical position, at any time, by ine'ans of the operating member or chain 6,.and through the instrumentality of the nuts 12. the effective length o'f the legs 11 may be adjusted, thereby to vary-the distance between the baffle 4 vand the bottom of the tank i.

in the form of bolts, nuts l2 being mounted by the numeral i6, the outlet being in the sidewall of the tank, instead ot in the bottom of the tank as depicted in Figure 3. The valve for the outlet is denoted by the numeral 18. Clamp members 19 hold the out let 17 on the wall oi" the tank 16. The baille is marked by the numeral 20 and has a del pending flange 2l supplied with a notch adapted-to receive the inner end of the outlet 17, the flange 21 of the baille beingI located between the inner clamp n'ieinber 19 and the wall of the tank, a gasket being interposed between the flange 2l and the `Wall ofthe tank. In Figure l the baille 4 is l beadjustedvertically through the instruvnientalit-yrofl the nuts 25, the notch 22 in the flange 2l permitting the necessaryv adjustment.,

It will be clear that the baille 20 will l constrain thesediment and lforeign matter to flow from the bottom of the tank through the outlet 17. a downward lilowing of oil l from the tank into the outlet 17, and a correspondingr 'In AFiguresS and 9, thetank is marked `by the numeral 26. the outlet 27 being in the bottom of the itank. j noted by the numeral 28 and is of circular dorm, the baille being located above the out- I 40 The baille is delet 27.

"Projections or pins 31 may be mounted in the bottom of the tank 26, the projections or pins being received in the boresiof thel legs 29, to hold the baille in place above the outlet 27.

An air pipe 62 extends downwardly through the top 53 of the baille 52 and discharges into the outlet pipe 5l, the air pipe carrying acheck valve 63 preventing a back ilow of liquid into theair pipe.

In Figures 1l and 12, the bottom of the tank is marked by the numeral 64 andthe outlet appears at 65. The ladder legs are shown at 66 a-nd a disk-like baffle 67 is provided, the same having outstanding ears (3S whereby the baille is mounted slidably on the ladder legs for raising and lowering. A brace bar 69 extends across the baille 67 and issecured thereto as shown at 75, the brace bar being provided at its ends with means 70 for engaging flexible elements 7l, suchas chains, whereby the baille may be raised and lowered.
